Trade vs Swap vs Exchange vs Change (Difference)
I wonder if these verbs "trade", "swap", "exchange", and "change" mean the same in the following context and I can use them interchangeably.

Examples:
1. My friend, Victoria, is very kind and is always there with a shoulder to lean on. I wouldn't TRADE her for anything.
2. My friend, Victoria, is very kind and is always there with a shoulder to lean on. I wouldn't SWAP her for anything.
3. My friend, Victoria, is very kind and is always there with a shoulder to lean on. I wouldn't EXCHANGE her for anything.
4. My friend, Victoria, is very kind and is always there with a shoulder to lean on. I wouldn't CHANGE her for anything.

5. My laptop is so fast, so nice and so powerful. I wouldn't TRADE it for anything.
6. My laptop is so fast, so nice and so powerful. I wouldn't SWAP it for anything.
7. My laptop is so fast, so nice and so powerful. I wouldn't EXCHANGE it for anything.
8. My laptop is so fast, so nice and so powerful. I wouldn't CHANGE it for anything.

Answer

Keef and Nicole, thanks for your explanations. That helped a lot.

Answer

"To swap" is commonly used to describe an exchange of goods.  There is an event called a "swap meet" where people trade their old things.  To say that you would not swap a person might be considered insulting to the person being discussed, because it makes them sound like property.  I think "trade" is the perfect word to use for the first sentence.

Answer

In the first 4 sentences, it is a common expression to say "I wouldn't trade him/her/it/them for anything."  Using swap or exchange would sound a bit odd to a native speaker.  Using "change" in that sentence would be okay, but it gives the meaning of not wanting to change her personality, rather than not wanting to trade her for someone else.

In #5-8, the sentences all would be okay, although again, "trade" would make the most sense and "change" would mean you wouldn't want to alter the laptop itself.
